Final answer:
The molars have large, broad, flat crowns with distinctive cusps and 3 or more roots. They are located at the back of the mouth and are used for crushing food.
Step-by-step explanation:
The molars play an important role in the digestive process. When we eat, the molars help break down the food into smaller, more manageable pieces. The large, flat crowns provide a larger surface area for chewing, while the cusps help with the grinding motion.
Additionally, the molars have multiple roots, which provide stability and support for these powerful teeth. This allows them to withstand the force exerted during chewing and grinding.
Overall, the molars are essential for efficient digestion. They help break down food into smaller particles, making it easier for the digestive system to extract nutrients from the food we eat.
